If you haven’t completed your survey yet, please do so ASAP! We need your shipping address by November 20th so we can ship your order on time. If you have not received your survey link, please fill out the form at https://goo.gl/forms/GQlyVP6HqzGsz4S73 so we can send it to you via the Kickstarter messages.

This form asks for your backer number and Kickstarter email. After that, I guess that you should receive the survey link by email.

Oh! Are you talking about Indiegogo? Do they also issue backer numbers as well? Nonetheless, if so, be patient because the Kickstarter orders will be fulfilled first, then they will take care of Indiegogo orders.
